SnapdragonQ
It's coffee o'clock!
I don't have anything helpful concerning the incubators but I used to have ducks. Muscovies, which don't actually need water or a pond generally to stay healthy because they are more like barnyard geese. However whenever I would have a sitting mom on a clutch I would be sure to put a fresh pan of water out near the end because I know ducks will purposely wet their feathers during what we call the lockdown period to bring extra humidity to the hatching clutch.Initially, I read that ducks needed a higher humidity so I was running it at 58%. After browsing around here and reading more, it seems like the (relatively broad) consensus is that 35-55% is good for ducks, chickens, and guineas (the stuff I'm trying to hatch). So I've been aiming for 45% now, dropping to that slowly over a few days.
But it's hard to keep it that low without letting it run dry or close to dry. I'd taken the manual as gospel so I hadn't let it get to that point. On the first candling, my girlfriend didn't get the lid closed completely (very easy to do if you don't check), and it went into the 40s being slightly ajar like that without having the temp drop below 99.5.
So I thought I'd ask folks with more (eg any) experience...
Is it okay to let it run without water for a while as long as the humidity reading is within the desired range?
Is it okay to leave the lid slightly ajar like that to help regulate humidity (assuming there's no change in temperature) ?
Right now, I've got 2 incubators running on little water with fully open vents, and one's at 49%, the other 47%. If I fill the water in them and do nothing else, they typically run to 58-62%
